Data Sheet 1_Biofouled microplastics exposure is associated with shifts in late-summer lip

Southeastern Greenland data from a 2024 experiment aboard the RRS Sir David Attenborough. It contains results from exposing wild-caught juvenile Calanus hyperboreus copepods to pristine and biofouled microplastics under feeding and food-deprived conditions. The dataset was created by Alena Sakovich and shared under a CC-BY-4.0 license.

Use Cases

• Assessing the impact of microplastic exposure on lipid mass based on experimental conditions described.
• Analyzing shifts in fatty-acid composition, such as long-chain monounsaturated fatty acids and docosahexaenoic acid, under different exposure contexts.
• Comparing seasonal lipid accumulation dynamics in control copepods versus those exposed to biofouled particles.
• Investigating the role of particle conditioning (biofouling) and food availability in shaping microplastic impacts on zooplankton physiology.

Strengths

• Data originates from a controlled shipboard experiment conducted in July-August 2024.
• Focuses on a key Arctic species, Calanus hyperboreus, critical for food-web dynamics and carbon sequestration.
• Explicitly compares effects of pristine versus biofouled microplastics under different feeding regimes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is relatively small at 740.6 KB, indicating limited scope.
